2004 Toyota Sienna Owner Comments

problem #5

Sienna 6-cyl

  • 34,322 miles


Rear lift gate struts replaced on 3/11/2008 by Toyota due to rear lift gate not staying open and closing down on top of us by itself. Rear lift gate struts replaced again on 12/18/2009 by Toyota due to the same thing happening. Rear lift gate struts are again failing as of 12/2012. Called Toyota about it and they will not replace them stating they are out of warranty. The rear lift gate opens slowly, then begins to close down on top of you by itself. The rear lift gate takes great force to stop it from coming down on top of you. The safety mechanism/auto reversal does not seem to work properly as it takes a very strong person to reverse it. A woman or child could easily be crushed by the rear gate as they may not be able to force it back up. Being that these new struts in 2009 were suppose to be "longer lasting" according to Toyota, they are having to be replaced much sooner than most consumers would expect. New struts being replaced every 3 years is not what the consumer expects of "longer lasting" struts. At some point, someone is going to get seriously hurt or killed by these defective rear lift gate struts.

About 5 months ago I realized the driver's side door started making a clicking noise when opening and closing. Last week I learned it was the welding that cracked inside the door frame. As per all the complaints on the internet I believe Toyota needs to reissue an extended warranty on this part.

Dashboard is cracked in multiples places, and I am concerned that this would allow the air bags to deploy unintentionally hence creating an accident. The situation with the cracks continues to the extent that there are cracks across the whole dashboard, again in multiple places.

Both the power sliding door and the manual sliding doors do not open. The first incident was that it was difficult to open the manual door and eventually it could no longer be opened. The power door, one day, would not close with the power. We closed it manually and it kept reopening. We turned off the power to the door and finally got the door closed. It no longer opens either with power or manually. After researching this problem online, it appears that there are numerous Toyota Siennas that have the same problem with the sliding doors. Also from researching, Toyota has not done anything about this problem other than to charge high prices to fix the doors and to tell people that it is very rare for these doors to stop opening. I feel this is a safety issue as if there was an accident, no one in the back could easily get out of the vehicle.

2004 Toyota Sienna. The van currently has only 5,660 miles. Odor problems from beginning and eventually, it was discovered that water has been continually flooding into the van from underneath. Water problem was supposedly corrected, but the van still has a strong moldy odor and people develop constant headaches when driving in van. Van was bought at 2,330 miles and misrepresented as a demo van, when actually it was pre-owned. Apparently previous owners were unable to use van because of being sickened by odor and now van is standing for same reason. Currently in talks with dealer and manufacturer regarding problem. Van needs to be returned to dealer/manufacturer. This is a problem that cannot be corrected since apparently there is mold from the water that was allowed to stand for almost a year, and this is a health issue.
